NBC has announced a number of new shows and renewals for the 2010-2011 season over the last week, but "Heroes" is not among them — the four-season superhero show has been cancelled, according to Entertainment Weekly.

The show, once a freshman hit which earned 14.5 million average viewers during its debut season, saw its ratings sink in the ensuing years, with February 8's season finale drawing only 4.4 million people.

A number of its breakout stars, including Hayden Panettiere, Ali Larter and Zachary Quinto, found a second home at the movies during the show's run, with Quinto's re-imagining of the role of Spock helping turn the "Star Trek" reboot into one of 2009's biggest hits. He'll return to the role in an expected 2012 sequel.

However, "Heroes" wasn't the only show to go this week.

As previously reported by AccessHollywood.com, NBC mainstay "Law & Order," which ran for a whopping 20 seasons, was also shown the door.

NBC's slate for fall 2010 includes the comedy "Perfect Couples," with Oliva Munn, Christine Woods and Kyle Howard; the drama "Outlaw," a Jimmy Smits starrer from Conan O'Brien's Conaco Productions; David E. Kelley's new legal drama "Harry's Law"; the comedy "Friends with Benefits" and "The Cape," a drama about a cop on the run who turns to a costumed identity to disguise his vigilante exploits.
